ABSTRACT:
The direct vapor depositing resin composition of the present invention comprises at least one selected from the group consisting of (A-I): a graft copolymer obtained by graft-polymerizing one or more monomers or a monomer mixture to a complex rubber-like polymer (G) composed of a polyorganosiloxane and a (meth)acrylate-based polymer and (A-II): a graft copolymer obtained by graft-polymerizing one or more monomers or a monomer mixture including an alkyl (meth)acrylate as an essential component to a rubber-like polymer (R) in which the content of diene units is 30% by weight or less in 100% by weight of the whole rubber-like polymer. The direct vapor depositing resin composition of the present invention can provide a beautiful bright appearance after direct vapor deposition of a metal, further, has high level mechanical strengths such as impact strength and the like, and weather resistance, and is also excellent in hot plate welding property with a transparent resin such as PMMA resins, PC resins and the like.
